In Windows, you can use Windows Firewall to block or unblock certain applications, but it doesn’t offer an easy-to-use interface for its advanced features. If you want to block an application from accessing the internet, you must go through the following steps:
1. Click the Windows Start Menu and open Control Panel
2. Select System & Security
3. Then in the Firewall section, you select “Allow a program through the Windows Firewall”
4. If the program you wish to block or unblock isn’t listed, you must click “Allow another program” to add it. Choose the application in the list and select “Add”. Else you must then browse the hard drive to find it, and so on. This seems complicated for the average user.
Firewall App Blocker makes the process very easy! Simply drag and drop the application you wish to block into the FAB window, or browse the hard disk to find it.That’s it!

here’s a Tip: to make access even easier, create a shortcut in the startmenu (C:\ProgramData\Microsoft\Windows\Start Menu\Programs) or on the desktop. then in the properties you can asign a hotkey! i use ctrl+shift+F
for whatever reason windows will gladly let you assing hotkeys on any shortcut in any folder, but then just ignore it..
Yes, thanks, it took a lot of time and research, but I eventually figured out how to a) create an exception to the User Account Control trigger that was making opening the program such a pain every time and b) created a quick launch icon for easy access. That’s almost exactly what I wanted, so that works for me. In this way I can open the program, toggle it to the whitelist, and then later open it to toggle back off when I want full access to the internet again. Thanks for the program.
a) You can use the program in white list mode. If an application connects to the internet in white list mode, you can find and disable this rule from the advanced windows firewall interface.For some Windows applications (edge for example) there is usually a firewall rule to access to the internet.
b) If we add the program to the system tray, it will run in the background and consume unnecessary system resources.
That’s why we didn’t add this feature. You can open the program by adding the shortcut to a place you can reach.For example, start menu or taskbar.
I tried Net Disabler first and it is exactly what I want in terms of being able to make it exist only in the system tray, activated with a right click. But I needed an exception for Spotify, so I tried this, but I can’t have it either a) always blocking everything else or b) open as a program that cannot be minimized to the system tray. Is there any way you could implement that the way it exists for Net Disabler? I would be so grateful, and happy to donate if you were able.
Please add options for specific profile (domain, private, public)! Now rules allow|deny ALL profiles.

Hi! Is it possible for the FAB to block a program that wants to access the Internet while installing the program?
Finally realized how to make a .vbs file pointing to a .lnk (with admin privileges) of a .bat file to allow the insane Whatsapp updates which creates new folders almost everyday…hehehehe…, i’ll post it here after sleep for a while. Trillons thx again to Sordum team for their marvellous tools!
@ AvenocturnO : Thank you
Impressiveeeee, 15 bucks more on the way right now!, thanks a lot for the Desktop Whatsapp attention!!!
@Elian and @Ricoh we noted them down , thank you.
Hello I checked /O 3 but it is disabling the Windows Firewall altogether. What I want is cmd command to disable access to Windows Firewall Advanced settings which is possible through the GUI interface in Firewall > Restrict Firewall Access but I dont want to configure it through the GUI.
